Patent GB-1272283-A (GB)
Title: Method for the transmission of information over lines having the character of bandfilters
IPC: H04L25/48
Filed: 1969-04-21
Abstract: 1,272,283. Digital transmission by amplitude, phase, or frequency modulation. MAGYAR TUDOMANYOS AKADEMIA AUTOMATIZALASI KUTATO INTEZET. 21 April, 1969 [24 April, 1968], No. 20308/69. Heading H4P. In a system for use on a line of limited bandwidth e.g. a telephone line, data is coded in conformity with rules such that frequencies of uniform signals have redundant signals inserted which are passed to the line through a filter band passing frequencies e.g. between 300-3400 Hz. At the transmitter a coding unit A receives signals on input 1 from stores, either in parallel form if coding is arranged in blocks, or serially if coding is continuous i.e. on a bit by bit basis. Signals on lead 2 request rest block or bit. The coding output is passed to line M through a band pass filter C e.g. 300-3400 Hz. At the receiver a correction filter and amplifier B suppress disturbances and pass it to a resolver E which reproduces the real and imaginary parts [cos #t and j sin #t] which are passed to an evaluating unit F which reproduces the sequence produced in A and passes it through line 7 to a decoder A<SP>1</SP> which eliminates the redundant bits in accordance with the coding rule. A synchronized clock signal appears on lead 8. If the decoder recognizes an error a signal is returned to a transmitter. Evaluating unit F may sense both phase and relative amplitude of the signals presented to it or such evaluation may be carried out by a digital circuit. For certain types of coding, the latter method may bear similarities to a phase discriminating receiver. In a block coding arrangement described a 5 bit code is converted into an 8 bit code such that the first bit is always "1" and a "0" never follows another "0", a table of such conversions being given in the Specification. Messages and/or blocks may also be headed by synchronizing characters which are recognized by the receiver. In an alternative arrangement decoding is performed on a bit by bit basis instead of in blocks. Other coding rules are envisaged in the specification. It is stated that the equipment will operate at an average speed of 2400 bauds and as an average of 800 redundant bits are produced for 2400 information bits there is a great probability of error recognition. The unit C may incorporate a number of known circuits, e.g. for connection to a telephone set &c. Transmission may be by amplitude, frequency or phase modulation but the received signal will be a sum of sinusoidal signals with different amplitudes and frequencies from which the real and imaginary parts are produced in the resolver. It is considered that the vector of the resolver output is rotating which is recognized by the unit F.

Title: Improvements in automatic knitting machines
IPC: D04B7/04
Filed: 1936-07-23
Abstract: 478,596. Knitting-machines. TENNANT, W. J. (Soc. Etablissenients Lebocey) July 23, 1936, No. 20479. [Class 74 (ii)] The needle-selecting cylinder 1 of a flat machine and the ratchet wheels 22, 23 for controlling it are carried by a carriage 4 which is given a rectilinear reciprocatory movement. The movement of the carriage is governed positively in both directions, and the cylinder 1 carries elements 16 acting directly on the butts of the needles. The carriage 4 is carried at its ends by guides 5, 6, resting on rollers 7, 8. One or more groups of eccentrics 9, 10, carried by a driving shaft 11, rock a shaft 14 through levers 12, 13, and so through another lever 15 impart the transverse linear reciprocation toward and away from the needles, and positively in both directions, to the cylinder 1. A ratchet wheel 22 and a cam 44 are rigid with the shaft of the cylinder, and a ratchet wheel 23, cams 25 and 26, and a circular plate 24, can rotate as a unit about the shaft. A pawl 27, carried on a pivoted crank 28, can rock the ratchet 22 one tooth and hence rotate the cylinder 1 in the reverse stroke of the carriage 4, except when an end 35 of a lever 34 is on a rise on the cam 25, so lowering a stop member 29 out of the path of the pawl by forcing down a spring- pressed slide block 32. The ratchet wheel 23 is similarly rocked by a pawl 40 carried on a crank 41, and controlled by a stop member 42, but, in this case, two slide blocks 49, 50 are provided, controlled by the cams 26 and 44. Thus, ratchet wheel 22 is controlled by cam 25 whilst ratchet wheel 23 may be controlled by either of cams 26, 44. The ratchet wheel 22 can also be rotated by a pawl 36 mounted on a fixed support 37. This pawl is controlled by a lever 38, and the lever allows the pawl to drop on to the ratchet whenever a gap occurs in the series of removable pins 39 which are carried on the ratchet and support the lever at its mid-point. A latch opening blade 17, Fig. 2, acting over' the whole width of the bed, is operated by a cam 21 on the shaft 11, through levers 18, 19. The invention may be applied to machines having one or two needle beds, and in the latter case the beds may be operated simultaneously or alternately and the machine can be used for passing automatically from rib to tubular fabric and vice versa. In one process, one or more rows of rib work are knitted by simultaneous operation of both beds. The beds are then operated alternately to produce tubular work, widenings and narrowings being meanwhile effected by the selecting mechanism.

[Class 27] Articles b, Fig. 1, are stored in two or more magazines a, each pile resting on inturned flanges e,f, Fig. 2, at the bottom of the magazine. The bottom article of a magazine is delivered by pulling out a corresponding drawer d, after prepayment, a pusher g at the back of the drawer delivering the article from the flanges e, f to the drawer, when this is nearly fully open. Each drawer has a pin f<1> engaging a forked arm g<1> of a bell-crank lever a<1> pivoted at b<1>, there being a lever a<1> for each drawer. The other arm of the lever a<1> is provided with surfaces c<1>, m<1>, n<1> as shown. When a drawer is pulled, the surfaces c<1> engages a corresponding pin dl on a locking bar e<1> common to all the drawers and released by the insertion of a coin so that it can slide. As the selected drawer is pulled out, other pins or abutments h<1> corresponding to the unopened drawers slide along the surfaces m<1> of their respective levers a<1> and prevent these drawers from being opened. The drawers are also controlled by the usual stop devices which prevent more than one drawer being pulled out at a time, these devices comprising strips p, q on the drawers co-operating with sliding blocking members o. The abutment h<1> corresponding to the drawer comes behind the surface n<1> of the actuated lever a<1>. When the drawer is closed again, the surface n<1> acts on the abutment h<1> and positively returns the locking bar e<1> to its initial position.

Title: Improvements relating to circular knitting machines with two-part needles
IPC: D04B15/32
Filed: 1967-05-04
Abstract: 1,138,255. Knitting-machines. FRANZ MORAT G.m.b.H. 4 May, 1967 [14 Feb., 1967], No. 20728/67. Heading D1C. In a circular knitting machine with tubular needles a jack is provided with a stepped top to operate on the needle butt 5a and the needle slide butt 5d and a cam surface after the knitting station is radially relieved allowing the jack to move outwardly so that only the butt 5d is engaged. As shown in Fig. 6 the jack 1 is urged into contact with a cam 33A by a spring 7. Selection of the jacks is done by an electromagnet which acts on spring strips 21 one being provided for each jack. If the the strip 21 is attracted by the electromagnet it is put outside a cam 27 (28) and the jack is urged by spring 7 into operation, if it is not attracted the jack is urged by the strip 21 out of contact with the cam 3BA (dot-dash position Fig. 6). When the jack rises it lifts both parts of the needle with its stepped top and after the yarn has been fed the jack moves outwardly into the relieved part 36f of cam 36 under the action of spring 7 so that the top step engages only the butt 5d thus holding it while the needle hook is moved down by a further cam (not shown). The jack then moves inwardly and all three parts are moved down to their initial position.
